ln the sweeping and collecting machine according to the present invention, and more especially according to the first forni of Construction of it, (Figs. l to 5), the dredge or the like may be of any known type, and 'may be forfinstance constituted, as shown in the drawings, by the chains 1 for the connection of the buckets 2, by the supporting drum 3,

drum 4, wnosel shafts 5 two longitudinal bearers 7 connected t0- gether by means of stay bolts 8),'A are cou pled together in their movement byf means of the chain 9 in engagement with the toothed wheels 10, 1l respectively keyed on 'thcshafts 5, l. But the dredge used in the present invention is different from the usual ones, as the back part of eechbucket l is provided with a flat brush or longitudinal comb 12, preferably of metallic plate or wire, which sa id chains 1, or directly fixed to cach bucket 2, so as to slightly project beyond the said buckets. (See Fig. 1 and the detail shown in perspective view a bucket 2 and its brush 12). In this form of construction of the machine, the buckets are suitably spaced the ones from the others, in order that the driver from his'place 19, may have a sufficiently free sight along the way.

The dredge is mounted on the front of the vehicle by means of diagonal stays 13. 14, 15 and uprights 16 connected to the frame 17 or' thc vehicle, so that the dredge is .flownwardly inclined toward the front thereof. The shaft 5 of the front drum .is placed at such a suitabledistance from the level of the road, that, while the buckets 2 in their-l lowest position remain at some distance from the ground in order to avoid any ol stacle to their motion and breakage inconsequence of stones or proyections ofl the road,

the brushes-l2 on the contrary, as they pro-` ject beyond the buckets, come in contact brush is vertically fixed to the lby Fig. 4, .which shows in the desired direction from the shaft 2O by means of the chain -21 and the toothed wheels 22, 23 respectively mounted on the shafts 6 and 20. The shaft 2O is driven by the same motor which drives the vehicle, by meansof a couple of toothed wheels '21, 25 respectively keyed on the shaft 20 and on the shaft 26, which shaft 26 in its turn is driven by the motor and transmits the stress to the back wheels 27 of the vehicle (Figs. 1,

v2). The rotation of the shaft 20 is trans-` mitted to the toothed wheel 23 preferably through a clutch 28, which ,may be operated by means of the lever 29 in order to inter rupt eventually the operation of the dredge. (Fig. 1). .Y .n

The dredge which 1s applied to the sweeping and collecting machine forming the object of the invention and constructed according to the 'first form of construction, presents also the following features: On eachend of the shaft 5 of the front drum is disposed a rotary disk 30 of suitable diameter to prevent the buckets 2 from touching the road surface when they are in their lowermost position during operation, while Y the rotary disks 30 run on the surface of the road. In order to prevent the shock of v the disks 30 against the surface of Athe road during the starting up of the vehicle, there may be adopted for the shaft 5 an elastic suspension as shown in detail in Fig. 5. In this case the shaft 5 of the drum 3 is not rigidly fixed tothe structure 7, but it is connected to theV arms 31 jointed at 32 to 4, the frame 17 of the vehicle, so that the-said -shaft may be displaced inside the oblong slots 7 of the ends of the longitudinal hea rers 7. The springs 33 connected to the lon gitudinal bearers 7 and to the projections 31 of the arms 31 push constantly downward the arms 3l and consequently the shaft 5. In order to insure the complete discharge of the buckets 2 intothe tank 18, there are provided one ormore shaking devices, constituted for instance by elastic arms 34 fixed to the axis 35 situated transversely above the tank 18. The said elastic arnis34, during the movement of the dredge come in engagement with the brushes 12, and are firstly depressed and then released, so that they are compelled to strike 'against the .bucket (shown in dotted lines inwFig. 1) vwhich bucket is on the point of beingdischarged.

From the .foregoing it will be easy to nnderstand the manner of working of the present machine. In fact, during the/Forward 'motion of the vehicle, the dredge .being driven in the indicated direction. the

buckets 2 come and take up the n'iaterial 36 lying on the surface of the road,"bnt theyl leave untouched a layer 36 the thickness of which is the saine as the distance of the buckets from the ground; (this has been invthe next bucket, and so on.

dicated by dotted lines in Fig. 1) but this layer is swept forward in the next moment by the brush or comb 12 which follows im Aing snow, and the motor which drives the whole machine is a mechanical one, preferably of the internal combustion type, it is suitable to lead tlfrou'gh the pipe-38 the exhaust products of the motor along the walls of the double wall 18"'of the tank 18 from which they go out from 39. This arrangef ment produces the heating of thesaid walls` and insures a partial melting of the snow,

which can so descend more'easily inside thetank 18 as well duringVthe filling up of it 'as during its diseharg i In the form 'of construction. of the machine as shown in Figs.v 6, 7` and`8` the` principal modification in the general ar rangement of the construction 'consists in the arra'hgementof the driversseat Von the front of the vehicle. In consequence of this arrangement, the drivers view is perfectly'.

free a d not hindered by the buckets of the dredg, u l nearo each other in ordertoincrease the speci moto'r 40, which, in distinction trom the first form of construction, is situated almost at lthe center of the frame 17, serves to drive e eiciency of the said dredge. The- 10o Y Yhich buckets may be disposed very the back wheels of the vehicle through thev`y usual change speed gear 4,1 and preferably by means of chains 42. The said motor, preferably of the internal combustionA type, may be started by means of theside crank 40', from which the stress is transmitted to the motor by meansofthe couple of bevel' wheels 40". The arrangement of the whole dredge or the like is slightly modified. In fact, the shafts 5^, 6 are not provided with drums, but each of them bears a couple ofV toothed wheels 3, and 4, respectivelyysyith which come invengagement the supporting chains 1 of the buckets Besides, the lower shaft 5, instead of being'.`elastically arranged in regard to the frame 17, is carried by the side -bearings 47 fixed to the said frame. (See the detail'atl Fig. 8). But the said shaft 5' is capable of being controlled in regard to its height, by displacing the hearings 5', h v means of thescrews 47', inside the slots 47 of 17. In consequence of such arrangement it is possible to change the distance of the buckets 2 from the sur- 1, reds-ee face ofl the road without ciian'ring the tenr non of lciiains l, because the slots 47" of a u nged peri'iendicularly to the ob- .ique pc on of the dredge. The upper shaft 6' is arranged slidably on the ends oi the longitudinal bearers 7 by n'ieans oi' bearings G', and. its position may be controlled byfineans of tension devices T serving to Obtain the 'l' l.

.Shake the bodyof the corresponding bucket,

which Vis so compelled to d Jrents.

. The control of the dredge is operated in such a manner that the transmission of the power of the motor is preferably directed o the front shaft e of the said dredge. This transmission, with a, great reduction of velocity, may i be eected for instance by means of the shaft 20u, which with its worm 3 engages he worm-gear A directly mountd on the inotor shaft. bv means of the toothed wheels 23 and the chains 21 the power is transmitted to the cot-hed wheels Q2 keyed on the counter Shaft 45, from which, by imams of the wheel 6 and the chain 4S, theznoreinent is trailsmitted to the toothed wheel keyed on "ie shaft 5! of the dredge. The hand operted claw coupling:r serving to interrupt Jmporarily the working of the dredge, 1s preferably arranged on the counter shaft 45, and serves to temporarily couple together the shaft and the toothed wheel 46 which is ischarge its conloosely mounted on shaft This arrangement is made for the purpose of enabling the operator tcfstart or'stop the dredge, or`

i other words, the running of the buckets, at any uimo while the machine is in motion. On the front sides of the vehicle there are drranged twowalls 49 preferably conA -tructed of metallic plate, which are curved outward and' may be substantially consid-l ered as extensions of the'Xed sille walls 50 Serving to close laterally the body of the redge. T,.e said walls 49 are preicraliily inged atflfjj to the side walls 50, and are revented i'oin swinging outwardly too far by means of any suitable device, as for iustancc chains 51 fixed toian eye 52 (see Fig.

l of the frame and attached to hooks 49 Xed to 49. The said walls 49 collect and direct'to the dredge' the niaterial (snow 'or 1e. like) which' lies Ialong the wayofdbe i/ehicld` and that in a ,greater er smaller ouantitylaceoi'ding to the greater or smaller From the shaft divergence of the said walls, as shown rcspectively in full and in dotted lines in Fig. T. lVhen the said walls are completely closed and their ends are brought into contact, as has also been shown in dotted lines in Fig. 7, they work as a snow plow, which position is of' great utility when the transport of the machine must be effected.

It is obvious that the invention may be applied to vehicles driven by any kind of -xnotor, and not only by an internal combustion motor as shown in the annexed draw-V ings, Fig. 7 and thatv the machine may be used not only for clearing away the snow on the roads of the towns, but also on the railways, when it acts as a snow plow as indicated in dotted lines Fig. 7.
